I bought mine from Girzzly Sports for 250 shipped to my door. Just so u know, Im 5"8 188 and got a medium/Large. Its pretty baggy on me, I probabbly could have gone with just the medium. I think they make them for height more then weight. Works fine though, I jumped in my pool several times with it on and kept me dry. The water temp was around 44 feet were freezing though

Both are great suits. I have an O'neill myself. The only difference I know of is the neck seal. The Bare uses latex, and the O'neill has neoprene. From my experience, the neoprene is more comfortable but may leak a bit more on certain falls. Then of course there's the price difference.

I love my bare drysuit, yeah the the seal are latex and are uncomfortable the first time but you can trim them or stick a 2liter in the neck seal for about ten minutes and let the latex stretch alittle. I have yet to have any water leak into my suit on a hard crash. Like Scott said it is all a personal choice, good luck in making your decision.
